Dear hackers,
I added documentation more and tap-tests about LRG.
Same as previous e-mail, 0001 and 0002 are copied from [1].
Following lists are the TODO of patches, they will be solved one by one.
## Functional
* implement a new state "waitforlsncatchup",
that waits until the upstream node receives the latest lsn of the remaining nodes,
* implement an over-node locking mechanism
* implement operations that shares initial data
* implement mechanisms to avoid concurrent API execution
Note that tap-test must be also added if above are added.
## Implemental
* consider failure-handing while executing APIs
* add error codes for LRG
* move elog() to ereport() for native language support
* define pg_lrg_nodes that has NULL-able attribute as proper style
